It’s a mediocre antenna for 5 or more bands. Everyone will have a different method of terminating the trap – wire loops through the ends, screw terminals like mineAndrey, callsign deleted Diamlnd, Belgorod My emailed response: Email Subscription You are not subscribed to this review.
Mouse-over images for a larger view This is the basic layout of the W, 3 traps on either side of a balun supplied.
Added 24 Octdiaond an incoming email: The very ends of the dipole legs terminate on plastic insulators and to provide for the adjustment tails, the wire length is effectively somehat shorter due to the initial 55cm fold-back, some of which is used for the knot.
Well, I have my antenne over 3 years now.
I apid more for the masts and for attaching well the masts to the wall. Other designs see the wire lengths between the traps shortened to fine-tune, which in itself is a very ww8010 and time consuming process.
I bought the Diamond W as my first HF antenna, intending to mount it in my attic.
One important aspect is the tuning in the 80m band. If your transceiver has an automatic ATU either internal or external, then it won’t be too much of an issue anyway – simply the efficiency of the antenna will drop as you operate further away from resonance. The leg shown horizontally above covers 3. The critical info here is the wire lengths in the table above as it gives a starting point for those who want to build their own version and have the ability to wind up and tune some simple coax traps.
Diamond W-8010
Once I used a w clone during the JOTA and it was producing sparks of over 10 cm at the end of the 20 metre legs, great for the scouts! Mine is hanging only 4m high and I can work the world, contest with nice scores and have great fun. The external coil is covered by a hard black epoxy-like covering and if you damage the covering then the trap is likely to fail after being subjected to wet weather.
It needs to be at least 2 meters distant from any wall or roof. I have taken a quick copy of the translated page and put it on my web site to make it easier for those of us who do not read the Dutch language. The apex is only 8m above ground incidentally 2.
With this thinking I have the folowing question: I use these values to clone the antenna for friends.

Of course, the same concepts can be applied to making up your own trap dipoles for other bands. My first traps were all high in frequency according to my GDO relatively accurate so that meant that I had to allow more coax initially. However I made a giant mess of my mast’s ropes and ended up with an infuriating disaster so I tore it all down and riamond a comet h and am happier.
Adjusting is simple, a lot easer than a W3DZZ as each tune is not influencing the diamlnd bands. Balun to 24MHz trap length P: So make the ends not too sharp, bend them back. You could try to remove the black ‘baked-on shroud’ and count the viamond on each diamon as they will have to be replaced anyway.
This is the basic layout of the W, 3 traps on either side of a balun supplied. Can I recommend it? The fact that I homebrew it, makes diamonf difference: I am sure many of the visitors to the web page will find your information helpful in either repairing or cloning the W Only the ends are a little sensitive the height and moisture. The details on the web page regarding extra bands and the other web page dealing with field day HF antennas and making up a trapped radial might help you.
The start hole is fine – just the “end hole” idea needs to be modified. For the price it is a good antenna.

Main Menu Home Latest News The terminals of the coils should also be water protected. Just make sure that you allow a long enough PVC former to provide some “slot length”. This works perfect on high power as the high voltage is only at the end of a adjustment element.
To cross-check on the impedance and SWR details, you need to look at the following extract from their sheet: This is a parts list for the W Take care that the insulation on the wire cannot be damaged or the tuned length will vary as it makes contact then open-circuits again with swaying in the wind. Here in Holland the houses have only a little garden mine is 15m so this antenna is ideal as you can bend the end and run 80 to 10 m without tuning from your city garden.
As I said, it is in my one-story attic, so it isn’t a DX hunter, but I’m on the air. This article has intentionally not been a “hold my hand” style because everyone does things differently. You can also use a spectrum analyser in place of the diode probe – however it must be fed via a series resistor of 5K to 10K to reduce the loading on the trap.
As this was built as an “add-on”, the extra wire elements of the new dipole were simply added “in parallel” to the existing dipoles at the balun.

Building and tuning was simple enough – although I did make it a bit little shorter for 80m that I would have liked no tuning stub for 80 either! It was a great performer on the higher bands but was lacking seriously on 40m and 80m. One tuning method gives slightly more “gain” than the other. I contemplated using RG58 but at the w power level, it just isn’t necessary. It is ok for radiation 50 to 60 degrees to each side of the maximum, so it covers well degrees in my humble opinion.
Assembly was pretty straightforward with the usual high quality parts from Diamond. Andrey, callsign deleted Russia, Belgorod.
